The purpose of the study was to determine the influence of learning environment on students' academic achievement in mathematics at senior secondary school level. Thus the study investigated some components of learning environment and their possible influence on students' academic achievement in mathematics. A sample of 337 randomly selected SS II students was taken from a population of 1682 students in Potiskum LGA, Yobe state. Data analysis was done using descriptive statistics as well as the t-test. The result shown that, there is significance difference between the mean performance of students taught in an ideal learning environment and that of students taught in a dull learning environment at 0.05 level of significance. The findings were discussed with a view to improving both the quality of learning environment and academic achievement in mathematics. In view of that therefore, recommendations were made for the improvement of the learning environment.
